Case Type   : 极致RTO-硬件故障类
Case Name   : 开启极致RTO，业务压力后备机进行build过程中备机网卡停止3分钟
Create At   : 2020/1/5
Owner       : @peilinqian
Description :
    1、开启极致RTO
    2、备机进行重建
    3、备机网卡停止3分钟
    4、备机重建结果
    4、重建失败，再次进行重建
    5、执行完成后，关闭极致RTO
Expect      :
    1、开启极致RTO成功
    2、备机开始进行重建
    3、备机网卡停止3分钟成功
    4、备机重建结果（可能成功或者失败，如果失败再次重建）
    4、重建失败，再次进行重建
    5、执行完成后，关闭极致RTO成功
